Five Potential NCAA Tournament Sleepers for 2026 (Bracket Busters)

Every year the NCAA Division I Men’s Basketball Tournament produces teams that outperform their seed and shock the bracket. These programs often aren’t traditional national championship favorites, but they have the ingredients necessary to make a serious run: experienced guards, efficient offense, and the ability to win tight games.

In many cases, the best sleepers are teams whose full-season résumé doesn’t tell the entire story. Injuries, late-season improvements, or lineup changes can make a team significantly stronger than its seed suggests. Once the tournament begins, those teams suddenly look far more dangerous than the committee’s bracket would indicate.

Heading into the 2026 NCAA Tournament, several programs stand out as potential sleepers capable of pulling off multiple wins. Whether it’s an underseeded power-conference team finally getting healthy or a confident mid-major that has been winning all season, these teams have the profiles of March Madness surprises.

Here are five teams that could make unexpected runs in the 2026 tournament.

1. UCLA

Seed: No. 7 – South Region

The UCLA Bruins men’s basketball may be one of the most dangerous underseeded teams in the entire tournament field. On paper, a No. 7 seed suggests a solid but flawed team. However, UCLA’s situation is more complicated than that. Injuries disrupted their lineup throughout much of the season, preventing the Bruins from consistently playing with their full rotation.

When their core group has been available—Donovan Dent, Skyy Clark, Trent Perry, Eric Dailey Jr., and Tyler Bilodeau—UCLA has performed at a significantly higher level than its overall record indicates. That lineup provides a balanced combination of scoring, playmaking, and defensive versatility.

The Bruins also benefit from strong guard play, which historically plays a major role in tournament success. Dent and Clark provide the backcourt leadership necessary to control tempo and handle pressure situations.

If Bilodeau returns fully healthy as expected, UCLA suddenly becomes a matchup nightmare for higher seeds. Teams often struggle against opponents that can stretch the floor offensively while maintaining defensive length and athleticism.

Bottom Line: If the Bruins enter the tournament close to full strength, they could perform much closer to a top-three seed than a No. 7, making them one of the most dangerous sleepers in the field.

2. Ohio State

Seed: No. 8 – East Region

The Ohio State Buckeyes men’s basketball are another team whose résumé may not fully reflect their current form. The Buckeyes have shown steady improvement late in the season, particularly on the offensive side of the floor.

During the closing weeks of the regular season, Ohio State’s offense began operating at a much higher level of efficiency. Their ball movement improved, perimeter shooting became more consistent, and the team began generating higher-quality scoring opportunities.

Injuries earlier in the year also played a major role in Ohio State’s inconsistent results. Center Christoph Tilley missed time during the season, and forward Brandon Noel had been sidelined for weeks before recently returning to the rotation. Noel’s return gives the Buckeyes additional frontcourt depth and rebounding strength.

Ohio State also demonstrated its ability to compete with elite teams during the Big Ten Tournament, where the Buckeyes pushed Michigan Wolverines men’s basketball to the limit in a close battle.

Tournament history shows that teams peaking late in the season often outperform expectations. Check out our guide to March Madness Bracket Betting.

Bottom Line: Ohio State faces a difficult bracket path, but if their offense continues trending upward, the Buckeyes could easily play the role of bracket-buster.

3. Arkansas

Seed: No. 4 – West Region

The Arkansas Razorbacks men’s basketball may not be a traditional sleeper due to their seed, but they still fit the profile of a team capable of making a deeper run than expected.

Arkansas has one of the most explosive offenses in the country. The Razorbacks play at a fast pace, create scoring opportunities in transition, and shoot effectively from multiple areas on the floor. Their ability to score quickly makes them difficult to defend for long stretches.

A key reason for Arkansas’ late-season surge has been the emergence of freshman guard Darius Acuff, who has developed into one of the most dynamic offensive players in college basketball. Acuff’s scoring ability gives the Razorbacks a legitimate star capable of taking over games when necessary.

Another major contributor has been Malik Thomas, who has stepped into a significant scoring role and provides additional offensive firepower.

While Arkansas’ defense has been inconsistent at times, teams built around elite offensive production and dynamic guard play often create chaos in the NCAA Tournament. Recent tournament history has shown that high-scoring teams can make surprising runs when they catch fire.

Bottom Line: Arkansas’ defensive inconsistencies create risk, but their offensive firepower makes them a legitimate threat to reach the tournament’s second weekend.

4. Santa Clara

Seed: No. 10 – Midwest Region

The Santa Clara Broncos men’s basketball may not be a household name nationally, but the Broncos possess many of the qualities that define classic NCAA Tournament sleepers.

Santa Clara finished the season 26–8, earning its tournament bid after a strong campaign in the West Coast Conference. The Broncos combine efficient offense with physical defensive play, a combination that can frustrate higher-seeded opponents.

One interesting aspect of Santa Clara’s statistical profile is that its overall metrics are skewed by a short stretch of poor performances early in December. During that brief period, the Broncos struggled against several opponents, which significantly impacted their season-long efficiency numbers.

Outside of that stretch, Santa Clara has performed at a level comparable to many high-major programs.

The Broncos also excel in two key areas that often determine upset victories: forcing turnovers and offensive rebounding. Creating extra possessions is one of the most effective ways for underdogs to neutralize talent disparities.

If Santa Clara can disrupt opposing offenses while generating second-chance scoring opportunities, they could quickly become one of the tournament’s most dangerous teams.

Bottom Line: A double-digit seed that forces turnovers and attacks the offensive glass always has upset potential. Santa Clara fits that profile perfectly.

5. Clemson

Seed: No. 8 – South Region

The Clemson Tigers men’s basketball may not immediately appear to be a Cinderella candidate, but their style of play makes them particularly dangerous in the NCAA Tournament.

Clemson plays a deliberate, controlled style that focuses on limiting turnovers and maximizing possessions. Teams that slow the pace of games often create uncomfortable situations for higher-seeded opponents who prefer faster offensive rhythms.

The Tigers also emphasize defensive rebounding and half-court defense, two elements that become extremely important in tournament basketball. When games become slower and more physical, teams with disciplined defensive structures often gain an advantage.

Unfortunately for Clemson, the team suffered a major setback when center Carter Welling tore his ACL during the ACC Tournament. Losing Welling reduces their frontcourt depth and rim protection. Check out the top sports betting sites for betting on March Madness.

However, Clemson still possesses enough size, experience, and defensive discipline to maintain its identity.

Their opening-round matchup against Iowa Hawkeyes men’s basketball could easily become a tightly contested battle of styles.

Bottom Line: Clemson’s methodical approach can shorten games and increase pressure on opponents, which is exactly the environment where NCAA Tournament upsets occur.
